EVANDER MOIVER GREGG, OF MARS BLUFF, SOUTH CAROLINA.

IMPROVEMENT IN GUN-WIPERS.

Specification forming part of Letters Patent No. 172,996, dated February1, 1876; application filed January 11, 1876.

To all-whom it may concern:

Be it known that I, EVANDER M. GREGG, of Mars Bluff, in the county ofMarion and State of South Carolina, have invented a new and ImprovedGun-Wiper; and I do hereby declare that the following is a" full, clear,and exact description of the same, reference being had to theaccompanying drawing, forming a part of this specification, in which-Figure 1 is a side elevation; Fig. 2, a side elevation, partly inlongitudinal section.

The invention relates to means for swabbing or wiping out a gun-barrel,so as to conveniently liberate and remove the adhering matter on theinside surface.

The invention consists in a piece of metal having at one end a socket,into which is screwed a bolt, between whose head and a flange arearranged a series of rubber disks, with spaces and washers between them.The attachment has also, at the other end, a socket, in which isfastened the lower end of the ramrod.

A represents a piece of metal, preferably round in shape, having aninternally-threaded socket, a, at one end, and a second one, or someother fastening device, a), at the other. Around the entrance of openinga is located a circular flange, a. B is a screw-bolt, provided,preferably, with a broad head, b, flat on its outer face. Thisscrew'bolt works in the socket a, and receives upon its stem the rub:

ber or otherwise flexible disks 0, that are compressed between theshoulder a and bolt-head b. Between every two of these is arranged aplain spacing-ring, D, that I preferably make of copper or other metal,or any rigid substance. The disks 0 are beveled nearand on both edges oftheir periphery, so that they will readily yield under pressure againstthe inside of the gun-barrel, and thus detach from its surface anyadhering matter. The latter will accumulate between the disks, and maybe afterward easily washed off. The disks can be expressed outwardly, soas to present a larger circumference, by simply screwing up the boltinto the socket a while, by removing the screw, the disks and washersmay be changed for those of a larger size.

Having thus described my invention, what I claim as new is Thecombination, with a bolt, B, of rod A, having threaded end socket a andcircular flange a the independent flexibledisks G, and the smallerspacing-rings D, all constructed and arranged substantially as and forthe purpose specified.

The above specification of my invention signed by me this 24th day ofDecember, 1875.
